What is an optimal way to update style? Deleting layer with old style and uploading layer with new style break webmap connection to this layer. Saving/Uploading QML is very inconvenient

Hello Joseph,
you don’t need to delete and re-upload anything.

  1. Select the style you want to update in NextGIS Connect interface
  2. Select the layer in QGIS project with new style configured
  3. Go to its contextual menu → NextGIS Connect → Update layer style

That’s it. Once you update the style, all web maps that include this layer will automatically use the updated styling.
